运维自动化之ansible playbook结合docker安装smokeping
本次介绍ansible的paly book结合docker进行虚拟机里安装2.6.8版本smokeping（apache版本是2.4.7）。
docker版本
09:26:53 # docker version Client version: 0.11.1 Client API version: 1.11 Go version (client): go1.2.1 Git commit (client): fb99f99/0.11.1 Server version: 0.11.1 Server API version: 1.11 Git commit (server): fb99f99/0.11.1 Go version (server): go1.2.1 Last stable version: 1.1.2, please update docker
ansible版本
09:28:13 # ansible --version ansible 1.4.3
1、查看docker已有镜像
09:25:55 # docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE ubuntu 3.0 6cee55276528 9 weeks ago 369.8 MB centos5 3.0 e08d23b09189 9 weeks ago 840.9 MB centos6 3.0 e94a3b24a19b 9 weeks ago 415.9 MB
可以看到有3个镜像，1个是ubuntu，1个centos5，1个centos6.我这里打算使用centos6来弄。
2、加载新容器
09:31:01 # time docker inspect $(docker run -d -p 22 -p 80:80 --name="smokeping" centos6:3.0 /usr/sbin/sshd -D)|grep -i address|awk -F '"' '{print $4}'
172.17.0.5
real 0m4.737s
user 0m0.038s
sys 0m0.054s
可以看到4秒就加载新容器完成，并且镜像为centos6系统，容器名为smokeping，开启了ssh服务，并且暴漏了22与80端口。
下面在从后端看看本机都运行了哪些容器
09:31:29 # docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 56b70c31a07e centos6:3.0 /usr/sbin/sshd -D About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 0.0.0.0:49156->22/tcp smokeping 846efb9e4d7a ubuntu:3.0 /usr/sbin/sshd -D 12 days ago Up 4 days 0.0.0.0:49167->22/tcp ubuntu-test1 b9a9e6f2caed centos6:3.0 /usr/sbin/sshd -D 3 weeks ago Up 4 days 0.0.0.0:49166->22/tcp zabbix-server 978fff134b18 centos6:3.0 /usr/sbin/sshd -D 4 weeks ago Up 4 days 0.0.0.0:49165->22/tcp centos6-test5
下面是ansible安装smokeping的部分
3、ansible安装smokeping的信息
09:34:06 # cat smokeping_install/vars/main.yml smokeping_dir: /usr/local/smokeping smokeping_version: 2.6.8 smokeping_user: admin smokeping_passwd: '()TF%penst*&MedHU'
可以看到smokeping安装目录是/usr/local/smokeping，安装版本是2.6.8，登陆的账户是admin，登陆密码是()TF%penst*&MedHU
4、下面是安装smokeping的playbook结构
09:36:25 # tree smokeping_* smokeping_delete ├── files │ └── delete_smokeping.sh ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── copy.yml │ ├── delete.yml │ └── main.yml ├── templates └── vars ├── main.xml ├── main.yml └── vars └── main.yml smokeping_install ├── files │ ├── rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm │ └── smokeping.tar.gz ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── copy.yml │ ├── delete.yml │ ├── install.yml │ └── main.yml ├── templates │ ├── config │ └── smokeping.conf └── vars └── main.yml 13 directories, 18 files
5、playbook安装smokeping的内容是
09:37:27 # cat smokeping_install.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- common
- pcre_install
- apache_install
- smokeping_install
6、playbook删除smokeping的内容是
09:38:01 # cat smokeping_delete.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- apache_delete
- pcre_delete
- smokeping_delete
下面是安装与测试过程
7、把docker新容器smokeping的ip加入到ansible的hosts里
echo "172.17.0.5">>/etc/ansible/hosts
8、安装smokeping
09:39:10 # time ansible-playbook smokeping_install.yml --extra-vars "host=172.17.0.5 user=root" -k
SSH password:

花费6分52秒完成，花费时间多的主要是yum安装基础库与使用epel安装smokeping依赖库。
9、安装后测试
查看smokeping
由于我做了安全认证，需要输入账户与密码，这个账户与密码就上文第3步的账户与密码
然后默认的其他网络监控（包括1、2、3线电信、移动、联通、铁通与教育网的节点监控已经做好）
如果有其他的监控需要自己来添加即可。
10、删除
